Maurya Dynasty: Historical Sources, Origins & the Rise of Chandragupta Maurya

In 326 BCE, as Alexander the Great’s armies swept through the Punjab region in a series of devastating military campaigns, a monarch named Dhanananda of the Nanda dynasty held firm control over central India and Bihar. While Dhanananda escaped the immediate threat of Alexander’s invasion, the political chaos it created opened an unexpected door for a young man named Chandragupta.

Greek and Roman writers referred to him as Sandrokottos or Androkottos. It was the British scholar Sir William Jones who first identified this figure as the Chandragupta of Indian texts — a discovery that gave historians their first firm chronological anchor for ancient Indian history. The dynasty Chandragupta founded, the Maurya Empire, stands as one of the greatest political achievements in the ancient world, and its history is reconstructed through a remarkable array of sources.

Historical Background: The Pre-Mauryan Context

Before Chandragupta’s rise, the Indian subcontinent was fragmented into numerous competing kingdoms. The Nanda dynasty, under the ambitious but widely disliked king Dhanananda, controlled the powerful Magadha kingdom in present-day Bihar. The Nandas were known for their vast treasury and large armies, yet Dhanananda’s reputation among his subjects was poor — a fact that Chandragupta himself reportedly exploited when speaking with Alexander.

The arrival of the Maurya dynasty marked a transformative moment in South Asian history. For historians, it was like a lamp suddenly lit in a dark room: the chronological sequence became clear, small fragmented kingdoms consolidated into a vast empire, and for the first time, a cross-referenced record between Indian and classical Western sources became possible.

Literary Sources for Mauryan History

The Maurya dynasty is fortunate to be documented across three major Indian religious traditions — Brahmanical, Buddhist, and Jain — as well as by contemporary foreign observers. This triangulation of sources, while sometimes contradictory, gives historians a fuller picture than is available for many other ancient civilizations.

• Brahmanical Texts: Puranas, Arthashastra, Mudrarakshasa, and the Mahabhashya offer political, dynastic, and social context.
• Buddhist Texts: Mahavamsa, Dipavamsa, Divyavadana, and Mahabodhivamsa document Chandragupta’s lineage and Ashoka’s reign.
• Jain Texts: Parishishtaparvan, Kalpasutras, and multiple Prakrit works connect Chandragupta with Jain tradition.
• Foreign Accounts: Greek and Roman writers including Megasthenes, Strabo, Pliny, Arrian, and Justin provide external perspectives

Brahmanical Literature

• The Puranas: Among all Indian texts, the Puranas are the most useful for constructing the Mauryan dynastic timeline. While the corpus contains 18 “Mahapuranas” (Great Puranas) as well as many minor texts, the ones most relevant to Mauryan history are the Vishnu Purana, the Bhagavata Purana, and the Markandeya Purana. Because the Puranas are religious texts composed within a Brahmanical tradition, they treat the Buddhist-leaning Mauryan rulers with some degree of disdain, but they remain invaluable for establishing the dynastic lineage and succession.
• The Arthashastra of Kautilya: Few texts are as central to understanding the Mauryan era as the Arthashastra, composed around 400 BCE. Its author, Kautilya(also known as Vishnugupta or Chanakya), was reputedly Chandragupta’s political mentor and chief minister. The name “Vishnugupta” appears in Kamandaka’s Nitisara, while the commentary on the Bhagavata Purana refers to him by all three names interchangeably. The Arthashastra spans approximately 4,000 verses, interspersed with sections written in prose. Though primarily a treatise on political theory — statecraft, economic policy, military strategy, and diplomacy — it sheds extensive light on the Mauryan state’s political, social, and economic organization. This makes it one of the most important primary sources for understanding how the empire actually functioned.
• The Mudrarakshasa of Vishakhadatta: The Sanskrit drama Mudrarakshasa(“The Signet Ring of the Minister Rakshasa”) by Vishakhadatta holds a unique place in Mauryan historiography. Although its exact date is contested, most scholars place it in the latter half of the 4th century CE or the early 5th century CE, suggesting it belongs to the Gupta period. The play’s storyline — though embellished with literary flourishes — is rooted in historical events and popular tradition. The plot dramatizes the downfall of the Nanda dynasty, Chanakya’s political maneuvering to place Chandragupta on the throne of Pataliputra, and the ultimate conversion of the Nanda minister Rakshasa to Chandragupta’s side. Beyond its narrative drama, the work offers insights into Mauryan-era politics, society, economics, and religion.

• Katya̋yana’s Vartika: Katyayana’s grammatical commentary, the Vartika, indirectly contributes to Mauryan history. Notably, it provides an interpretation of the phrase Devanampriya (“Beloved of the Gods”), a title famously used by Emperor Ashoka in his rock edicts.

• Patanjali’s Mahabhashya: Patanjali, a contemporary of the Shunga king Pushyamitra, wrote the Mahabhashya— a major commentary on Panini’s grammar (Ashtadhyayi). He witnessed the Greek (Yavana) incursions during the reign of the weak Mauryan king Shalisuka, and his work sheds light on the political and social decline of the Maurya dynasty in its final decades. Intriguingly, the Mahabhashya records that late Mauryan rulers manufactured and sold divine images (deity statues) as a means of raising revenue — a striking detail that reflects the empire’s economic crisis.

• Plays by Bhasa and Kalidasa: The playwright Bhasadrew on pre-Mauryan storytelling traditions, making his works useful for understanding the broader Magadha cultural milieu. Similarly, Kalidasa’s Malavikagnimitram — while not directly about the Mauryas — depicts the early Shunga period immediately following Mauryan collapse. Its protagonist Agnimitra was the son of Shunga founder Pushyamitra, and the play illuminates the dying days of Mauryan power.

• Banabhatta’s Harshacharita & the Kathasaritsagara: Banabhatta’sHarshacharita describes the alleged conspiracy of Pushyamitra against the last Maurya ruler Brihadratha, whose murder ended the dynasty. The Kathasaritsagara (Ocean of Rivers of Story) by Somadeva and the Brihatkathamanjari by Kshemendra — both 11th-century Sanskrit compilations based on the earlier Pali work Brihatkatha — offer alternative accounts of Chandragupta’s origins. Finally, the 12th-century chronicle Rajatarangini by Kalhana documents Ashoka’s role as a ruler of Kashmir.

Buddhist Texts

Buddhist sources are among the most generous in their treatment of the Mauryas, particularly because Emperor Ashoka became one of the greatest patrons of Buddhism in history. The most useful Buddhist texts for Mauryan history are the Mahavamsatika (also called Vansatthappakasini), composed around the mid-10th century CE, and the Mahabodhivamsa, composed by Upatissa in the later 10th century CE.

Both works draw on older Sinhalese chronicles — the Sihalattakatha and the Uttaraviharattakatha. The Sihalattakatha is traditionally attributed to the Thera Mahinda (Ashoka’s son) and other monks who traveled from Magadha to Sri Lanka to spread the Dharma.The Mahavamsa, Dipavamsa, and Divyavadana further enrich the picture. The Mahavamsa explicitly identifies Chandragupta as a member of the Moriya (Maurya) Kshatriya clan, while the Divyavadana refers to both Bindusara (Chandragupta’s son) and Ashoka as consecrated Kshatriya kings.

Key Passage from the Mahavamsa

The Mahavamsa records: “Chandragupta was born into the illustrious Moriya clan of the Kshatriyas — a lineage established by the sons of the Shakyas.” This identification of the Mauryas with the Shakya clan of the Buddha was of great importance to Buddhist writers, as it connected the imperial dynasty to the Buddha’s own royal lineage.

Jain Sources

Jain texts — available in both Prakrit and Sanskrit — are likewise valuable for reconstructing Mauryan history, though the two major Jain sects (Shvetambara and Digambara) sometimes offer divergent accounts.

Among the Digambara texts, the most significant are Harisena’s Brihatkathakosha, Prabhachandra’s Aradhana Satkathaprabandha, and Nemichandra’s Kathakosha. These works narrate the story of Chanakya and Chandragupta in considerable detail. Other useful Digambara texts include the Harivamsha Purana, Uttara Purana, Trilokasar, and Dhavala.

Among Shvetambara texts, the canonical Agama scriptures and their commentaries are particularly important. Haribhadra’s commentaries on texts like the Uttaradhyayana Sutra, Avashyaka Sutra, and Dashavaikalika Sutra preserve important Mauryan-era narratives.

Bhadrabahu’s Kalpasutra and Hemachandra’s Parishishtaparvan are the crown jewels of Jain sources on the Maurya period. The 14th-century text Vicharashreṇi by Merutunga also contains Mauryan material.

Jain texts are notable for connecting Chandragupta with peacocks (mayura), consistently describing his mother’s family as peacock-keepers — a detail that aligns with the dynasty’s totemic symbolism and the Buddhist Moriya (peacock) clan tradition.

Greek, Roman & Chinese Accounts

Classical Greek and Roman Writers

Among foreign sources, the accounts of Greek and Roman writers are the most historically precise for the Mauryan period, primarily because some of them were direct contemporaries or near-contemporaries of Chandragupta. Alexander’s own campaign companions — Nearchus, Onesicritus, and Aristobulus — left accounts of the India they encountered. These were later supplemented by the writings of ambassadors dispatched to the Mauryan court by Greek rulers. Of these, Megasthenes (who served as Seleucid ambassador to Pataliputra) wrote the most famous account: the Indica. Although the original work is lost, extensive fragments survive in the writings of later authors.

Strabo (c. 64 BCE – 19 CE), in the 15th book of his Geography, dedicates the first chapter to India, drawing on Megasthenes and Alexander’s companions to describe the subcontinent’s geography, customs, and people. Diodorus (died c. 36 BCE) compiled an account of India based on Megasthenes.

Pliny the Elder’s encyclopedic Natural History (published c. 75 CE) blends Greek sources with reports from contemporary merchants. Arrian (c. 130 CE) produced what many consider the best account of Alexander’s campaigns in his Anabasis. Plutarch (c. 45–125 CE), in his Lives, devotes chapters 57–67 to Alexander’s biography, including material on India. Justin’s 2nd-century Epitome contains the famous passage describing Chandragupta’s early life and his encounter with Alexander.

William Jones’s Landmark Identification: The decisive breakthrough in Mauryan chronology came when Sir William Jones, in 1793, identified the Greek Sandrokottos with the Indian Chandragupta. This identification created an immovable chronological peg: since Chandragupta was demonstrably a contemporary of Alexander (who died in 323 BCE) and Seleucus I (who signed a peace treaty with Chandragupta around 303 BCE), the entire timeline of ancient Indian history could be calibrated from this single anchor point.

Chinese Pilgrim Accounts

While the Chinese Buddhist pilgrims Faxian (Fa-Hien, c. 399–414 CE), Xuanzang (Hsuan-tsang, c. 629–645 CE), and Yijing (I-Tsing, c. 671–695 CE) traveled to India centuries after the Mauryan period, their travelogues contain incidental references to Mauryan-era monuments, legends, and cultural memories.

Faxian personally visited and recorded several stupas attributed to Ashoka. Xuanzang documented the founders and traditions associated with religious sites across the subcontinent, preserving oral histories connected to the Mauryan era.

Archaeological Evidence

For all their value, literary sources are ultimately composed by human authors with particular biases, agendas, and temporal distances from the events they describe. Archaeological evidence offers something different: material artifacts and inscriptions that speak with greater immediacy.

The most significant archaeological sources for Mauryan history are the approximately 40 inscriptions of Emperor Ashoka, found across India, Pakistan, and Afghanistan. These rock edicts and pillar inscriptions — composed in Prakrit (and in some western provinces in Greek and Aramaic) — are the primary evidence for Ashoka’s reign, his embrace of Dhamma (righteousness), his governance, and his family. R. G. Bhandarkar’s landmark work, Ashoka, was built primarily on this inscriptional evidence.

Beyond Ashokan inscriptions, several other epigraphic sources illuminate Mauryan history. The Hathigumpha inscription of King Kharavela of Kalinga (modern Odisha) sheds light on the political decline of the later Mauryas. An inscription on Chandragiri Hill near Shravanabelagola (Karnataka) provides evidence for the tradition that Chandragupta spent his final days there as a Jain ascetic, dying by ritual fasting (sallekhana).

The Junagadh rock inscription of Rudradaman (c. 150 CE) records that a Mauryan provincial governor named Pushyagupta (described as a Vaishya) constructed the famous Sudarshana Lake in Gujarat during Chandragupta’s reign. The cave inscription on the Nagarjuni Hills refers to a Mauryan ruler named Dasharatha. Taken together, the physical remains — stupas, viharas, pillars, palace ruins at Pataliputra, and terracotta sculptures — flesh out our understanding of Mauryan society and material culture.

The Origins of the Maurya Dynasty: Debating Chandragupta’s Lineage

Few questions in ancient Indian history have generated as much scholarly debate as the social origins of Chandragupta Maurya. The primary Indian textual traditions — Brahmanical, Buddhist, and Jain — are not in agreement, and modern historians have staked out distinct positions.

The “Shudra Origins” Argument — and Its Problems

The claim that Chandragupta was of Shudra birth rests primarily on Brahmanical texts. The Vishnu Purana famously states that after the last Shaisunaga-dynasty king Mahanandi, “kings of Shudra birth will rule the earth” — but this statement applies directly to the Nandas, not necessarily to the Mauryas who succeeded them.

The Mudrarakshasa calls Chandragupta vrishala (“bull among men” or sometimes “low-caste”) and kulahina (“of inferior lineage”). However, as the Sanskrit scholar tradition makes clear, vrishala in texts like Manusmriti and the Mahabharata simply means “one who has lapsed from righteous conduct” — not necessarily a Shudra.

In Mudrarakshasa itself, Chanakya uses the term for Chandragupta almost affectionately, and at one point calls him “the foremost among kings” (raja vrishabha). The 18th-century commentary by Dhundhiraja, which elaborately constructs a story to make Chandragupta Shudra-born, has no earlier corroboration and is now regarded by most scholars as largely fictional.
